z= File hand tools with strip-shaped multi-blade are mainly used for micro-processing of metal, wood, leather and other surface layers. According to different cross-sections, they can be divided into flat files, round files, square files, triangular files, diamond files, semi-circular files, etc., also called files. Triangular files can be further divided into flat triangular files, ordinary triangular files, narrow triangular files, extra narrow single-grain triangular files, heavy-duty triangular files, etc.
We use aluminum bronze alloy and beryllium bronze alloy as raw materials to produce triangular files, which are processed through multiple processes. The surface treatment of the product has a variety of forms for customers and friends to choose from. Explosion-proof tool products Surface treatments include natural color, electrostatic spraying, etc. The tensile strength of processed flat files made of beryllium bronze can reach over 100 degrees, and products made of this material are both explosion-proof and anti-magnetic. Aluminum bronze alloy products can reach temperatures above 100%, and can definitely meet the needs of customers and friends for triangular file products according to their different needs.
